TELESIN CPL ND 8 16 32 Filters Kit is an essential accessory for any photographer's camera bag. It reduces the amount of visible light that enters the lens, allowing the user to utilize wider apertures or slower shutter speeds, particularly in bright conditions. It works especially well for portraits by allowing the photographer to reduce the depth of field, producing pleasant background blur while keeping the subject in sharp focus. This particular filter is multi-coated to minimize reflection on the filter surface, which reduces flare and ghosting, and produces sharp contrast and well-balanced color. These filters are also often used to emphasize movement by permitting slow shutter speeds in bright light, giving life to photos that would otherwise look frozen in time.
